I m 使用以下代码读取来自 parcel 的 < code> HashMap< String, string, 字符串 类型的地图 :
in.readHashMap(HashMap.class.getClassLoader());
这似乎很好, 但我得到一个警告:
Type safety: The expression of type HashMap needs unchecked conversion to conform to Map<String,String>
是否有一种“ 正确” 的方式来做到这一点, 使用不同的类装载器吗? 还是我应该使用 < code\ presswarnings ("未检查" )?
Parcel.readHashMap() 的机器人开发者文件写道:
Please use
readBundle(ClassLoader)instead (whose data must have been written withwriteBundle(Bundle).
所以也许你应该使用 readBundle () 和 writeBundle () 。
